868MHz 500mW high power si4431 wireless moduleDesigned by DORJI, Ships from China
Features: FSK/GFSK Modulation 868 transceiver module 27dBm output power -122dBm sensitivity Standard SPI interface Temperature sensor and 8-bit ADC Data Rate: 0.123~256 kbps Transmit current: 320m...Read More…
DRF4431F27 is also based on SI4431 from Silicon labs. The -122dBm sensitivity and 27dBm output power make the module suitable for long range applications. DRF4431F27 module consists of RFIC Si4431, thin SMD crystal, LDO and PA circuit. The antenna port is well matched to standard 50 Ohm impedance. Users don't need to spend time in RF circuit design. It is fully compatible with DRF4431F13 and DRF4432F20 modules. Users can design products with suitable modules and easily replace them with other family modules in the future when applications have different requirements on distance.
Kindly note that DRF4431F27 shares the same PCB board with 433MHz module DRF4432F27 so the silkcreen on the back of PCB is also DRF4432F27 but the circuits of them are different.
